Consider the following distribution of daily wages of 50 workers of a factory. \( \begin{array}{|c|c|} \hline \text{Daily wages (in ₹)} & \text{Number of workers} \\ \hline 500 - 520 & 12 \\ \hline 520 - 540 & 14 \\ \hline 540 - 560 & 8 \\ \hline 560 - 580 & 6 \\ \hline 580 - 600 & 10 \\ \hline \end{array} \) Find the mean daily wages of the workers of the factory by using an appropriate method.
